Patch by Bill Seurer; some comment formatting changes by me. There are a few PowerPC test cases for FastISel support that currently fail with VSX support enabled. The temporary workaround under discussion in http://reviews.llvm.org/D5362 helps, but the tests still fail because they specify -fast-isel-abort, and the VSX workaround punts back to SelectionDAG. We have plans to fix FastISel permanently for VSX, but until that's in place these tests are preventing us from enabling VSX by default. Therefore we are adding -mattr=-vsx to these tests until the full support is ready. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220172 91177308-0d34-0410-b5e6-96231b3b80d8

; FIXME: FastISel currently returns false if it hits code that uses VSX
|
|
; registers and with -fast-isel-abort turned on the test case will then fail.
|
|
; When fastisel better supports VSX fix up this test case.
